The ixStrip method on the Vault class creates a transaction instruction that strips SY tokens into equal amounts of PT and YT.
This method takes SY tokens directly. If you want to strip from a base asset (e.g., USDC), use ixStripFromBase instead.

​
Usage

import { Vault, LOCAL_ENV } from "@exponent-labs/exponent-sdk";
import { Connection, PublicKey, Transaction, sendAndConfirmTransaction } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const vault = await Vault.load(LOCAL_ENV, connection, vaultAddress);

const ix = vault.ixStrip({
  syIn: 1_000_000n,
  depositor: wallet.publicKey,
});

const tx = new Transaction().add(ix);
const signature = await sendAndConfirmTransaction(connection, tx, [wallet]);

​
Required Parameters

ParameterTypeDescription
syInbigintAmount of SY tokens to strip
depositorPublicKeyThe depositor’s wallet public key

​
Optional Parameters

ParameterTypeDescription
sySrcPublicKeySource SY token account. Defaults to depositor’s ATA
ptDstPublicKeyDestination PT token account. Defaults to depositor’s ATA
ytDstPublicKeyDestination YT token account. Defaults to depositor’s ATA

​
Returns

Returns a TransactionInstruction that strips SY into PT and YT. The number of PT and YT minted equals syIn × exchangeRate.
